Title: Improvements in or relating to piston ring assemblies
Inventor: GUNNER HAROLD
IPC: F16J9/06
Filed: 1955-07-13
Abstract: 773,268. Piston-rings. LIGHT PRODUCTION. Ltd. July 13, 1955, No. 20351/55. Class 122 (1). A piston ring assembly comprises a pair of thin split rings 16 adapted to engage opposite sides of the piston-ring groove and urged radially outwardly by a split expander ring of wavy formation in plan provided on each side of ts radially inner crests with axially extending lugs 11 on which the rings 16 are supported at their inner peripheries. The expander ring is made from spring steel strip having rectangular openings 10, separated by parts 12, and lateral lugs 11 symmetrically disposed with respect to the openings, and bent first into sinuous shape and then into a circle with the radially flanged ends 18 abutting. The inner curved peripheries 15 of the split rings 16 are supported on the faces 13 of the lugs 11 and the inner radial faces of the rings 16 are supported by the narrower portion of the expander ring. The outer peripheries 17 of the rings 16 may also be curved. The width across the lugs 11 is slightly less than that of the piston-ring groove and the complete assembly is a push fit in the groove, the expander ring being axially resilient due to the openings 10 and of such circumference that with its ends 18 abutting it will not bottom in the groove. In a modification, the waves of the expander ring are rectangular and the edges 19, Fig. 6, of the narrower part of the ring converge outwardly, the width of the assembly being slightly greater than that of the piston-ring groove so that when it is sprung in the latter, the splitrings 16 lie substantially flat against the edges 19.

Title: Improvements in or relating to processes of producing or preparing a concentrate of naturally occurring vitamin e and antioxidant from a vegetable oil, and the concentrate resulting therefrom
IPC: A61K31/355
Filed: 1939-07-14
Abstract: 531,226. Glycerine; stabilizing fats. GENERAL MILLS, Inc. July 14, 1939, No. 20568. Convention date, July 18, 1938. [Class 91] [Also in Group IV] To produce an anti-oxidant for fats, the glycerol of the glycerides present in wheat-germ or like oil is replaced by methyl, ethyl or propyl alcohol by treatment with these alcohols and hydrogen chloride, the excess alcohol is distilled off, the glycerol layer is removed, and the esters are washed and cooled to separate sterols and then distilled under high vacuum, leaving a residue which is the anti-oxidant concentrate. Further concentration may be effected by saponifying the concentrate and extracting with a solvent such as ether, chloroform or ethylene dichloride or converting the saponified product to calcium soaps and extracting with acetone. In an example, wheat-germ oil is heated with hydrogen chloride in methanol under reflux and the ester layer is separated from the glycerol and washed with hot salt solution and chilled to 0-5‹ C. to separate sterols. The filtrate is distilled under high vacuum and the distillation residue is saponified with caustic soda in methanol and diluted with hot water. Calcium chloride is added to precipitate a calcium soap, which is separated and extracted with acetone, the extract being cooled to separate sterols, whereafter the residual solution is evaporated to remove water and acetone. The residue may be still further concentrated by extracting with petroleum ether, the extract being cooled to separate sterols and then evaporated. Instead of distilling the methyl esters and then saponifying the saponification may be effected first, the saponified product being treated with calcium chloride ; the calcium soap is then extracted with acetone as described above.

Abstract: 149,012. Huth Ges., Dr. E. F. Nov. 15, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic relays and repeaters.-A device .acting as a mono-telephone comprises a thermionic valve with a tuned circuit associated with its gridfilament circuit, and a correspondingly tuned circuit connected in its plate circuit, the input potential being applied in the plate circuit across the condenser and inductance of the tuned circuit. As shown in Fig. 2, the input circuit comprises earthplates 12, 13 connected across the terminals of a circuit 9, 16 tuned to the desired audible frequency. The plate battery 7 is shunted by a condenser 8, and the telephone 10 by a condenser 11, thus forming if desired a resonant circuit 10, 11. The grid circuit is connected by a transformer to a tuned circuit comprising a variable condenser 15. A resistance 17 in this circuit may be varied for the purpose of adjusting the sharpness of resonance. A reactive coupling circuit may be arranged between a coil 18 in the plate circuit and the grid transformer, but this is not essential. If this reactive coupling is made sufficiently tight, the valve produces vibrations which may be utilized to interfere with the received vibrations, producing a beat note in the telephone.

Abstract: 406,721. Trap - shooting. JACKSON, H. E., 20, Wake Green Road, Moseley, Birming- ham, and IMPERIAL CHEMICAL INDUSTRIES, Ltd., Millbank, London. July 28, 1932, No. 21340. [Class 132 (i).] A trap for throwing clay targets of the kind in which the throwing arm is operated by a spring and after making a partial revolution discharges the target and is then reset by hand is characterised in that the throwing arm is adapted to rotate in one direction only, oscillation being thereby prevented and the momentum of the arm being utilised for a partial re-setting of the trap, which is completed by hand. As shown in Fig. 1 at one end of a cylindrical housing 1 is a pin 2 forming the fulcrum of a lever 3 which moves in a complete circle. The outer end of this lever comprises a handle 4 adjacent to which is attached a hand 5 for holding the target 6. The supporting casting 7 is bored to fit a pin 8 attached to the base 9. In order to rotate the body of the trap the lever 10 is raised by pivoting about the front projection 11. Horizontal setting is secured by lowering the lever into the notches in the base plate 9. The trap may be pivoted in a vertical plane about the pin 12, and may be locked by a screw 13. The throwing arm is released by means of a lever 14 pivoted at 15 and held in position by the spring 16. A hole 17 serves for the attachment of a cord. As shown in Fig. 3, the pin 2 carries a toothed quadrant 19 and a crank pin 20, connected to which pin is a rod 21 passing through the centre of the volute spring 18 and the body 1 and has a nut 27 at its outer end for adjustment of the compression of the spring, a stop 26 on the rod 21 limiting such adjustment. After release of the target, the arm 3 continues to travel past the centre line of the body until the spring is partially re-compressed, and backward movement is prevented by the engagement under spring pressure of a pawl 22 with the quadrant 19. Specification 406,722 is referred to.
